Đã phân lập, định danh được các chủng Salmonella từ thịt lợn, thịt bò,
và thịt gà tại các chợ bán lẻ ở Hà Nội. Các mẫu nghiên cứu nhiễm
Salmonella với tỷ lệ 27,8%, bao gồm 9 serovar khác nhau, trong đó phổ
biến nhất là S. Typhimurium.
2. Đã xác định được đặc điểm kháng kháng sinh của các chủng Salmonella
phân lập được. Salmonella phân lập được có tỷ lệ đề kháng kháng sinh
hay sử dụng là 52%, tỷ lệ Salmonella đa kháng kháng sinh là 36%. Các
kháng sinh bị đề kháng cao là STR và TE (44%). Ngược lại, 100% số
chủng nhạy cảm với CAZ. Kiểu hình kháng kháng sinh phổ biến là TE,
STR, AM, và C, TE, SXT, STR, AM.
3. Đã phân tích được các nhóm gen ở các chủng Salmonella đa kháng kháng
sinh. Bao gồm các nhóm gen liên quan đến kháng kháng sinh và các
nhóm gen liên quan đến độc tố của vi khuẩn. Từ đó đã xác định được:
• Đột biến mới ở gen parC (A628S) có khả năng liên quan đến đề kháng
kháng sinh nhóm quinolone ở Salmonella
